Machine for pressing a fastener through sheet metal studs

Abstract

A machine for pressing a fastener through sheet metal with a magazine for holding a strip of fasteners that self load semi-automatic, a clamp for loading the fastener, and holding material to be fastened, a fastener barrel guide to establish proper position of the fastener to be installed, a first stage low power source to provide pressure for loading the fastener and clamping the material, a second stage high power source for installing and securing the fastener, a lock seat set opposed to the clamp, to hold the opposite side of the material and the second part of the fastener component. A preferred embodiment includes a lock seat for holding the second part of the fastener. A preferred embodiment includes a removable lock seat, so that the tool will have the ability to use different type lock-seats, therefore allowing the same tool the capability of installing different type fasteners.

What is claimed is: 
     
       1. A portable machine for pressing a two part fastener through material comprising: a portable tool having a tool frame;   a magazine in said tool for holding a plurality of first fasteners;   a base in said tool frame for holding a mating second lock fastener for engagement with one of said first fasteners;   a barrel clamp for loading and positioning one of said first fasteners and for holding the material to be fastened;   a first stage low power source to provide pressure to said barrel clamp for loading the first fastener and clamping the material;   a lock seat set opposed to the clamp to hold the opposite side of the material and said second fasteners; and   a second stage high power source for causing penetration of the material by one of said first fasteners and mating with said lock fastener on the opposite of said material.   
     
     
       2. The portable machine of claim 1 further comprising a remote controlled low and high pressure hydraulic power system for pressing said first and second fasteners. 
     
     
       3. The portable machine of claim 1 wherein said lock seat is removable. 
     
     
       4. The portable machine of claim 1 further comprising a proximity switch to prevent said second stage high power source from activating when the barrel is obstructed. 
     
     
       5. The portable machine of claim 1 further comprising a proximity switch to energize the high pressure power source automatically for installing said fasteners. 
     
     
       6. The portable machine of claim 1 further comprising means for automatically de-energizing the high pressure power source.
